My first handgun bought specifically for carry was a HKUSPC. Still too damn big. Replaced it with a 3" 1911 that I still carry, as it is perfect. I would opine that most will gravitate toward smaller rather than bigger, with a few exceptions, the longer they carry, as long as they are satisfied with performance and are willing to trust their life to it.
